IE8 supports function.bind() method

<script type="text/javascript"> 
if (!Function.prototype.bind) { 
Function.prototype.bind = function (oThis) { 
if (typeof this !== "function") { 
throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable"); 
} 
var aArgs = Array.prototype.slice.call(arguments, 1), 
fToBind = this, 
fNOP = function () {}, 
fBound = function () { 
return fToBind.apply(this instanceof fNOP && oThis 
&#63; this 
: oThis, 
aArgs.concat(Array.prototype.slice.call(arguments))); 
}; 
fNOP.prototype = this.prototype; 
fBound.prototype = new fNOP(); 
return fBound; 
}; 
} 
</script>

Mainly solve the bug in the example on the "Baidu Map" official website, extract the following code:

 
 
 
 
 
 
 
 
给多个点添加信息窗口 
<script type="text/javascript"> 
if (!Function.prototype.bind) { 
Function.prototype.bind = function (oThis) { 
if (typeof this !== "function") { 
throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable"); 
} 
var aArgs = Array.prototype.slice.call(arguments, 1), 
fToBind = this, 
fNOP = function () {}, 
fBound = function () { 
return fToBind.apply(this instanceof fNOP && oThis 
&#63; this 
: oThis, 
aArgs.concat(Array.prototype.slice.call(arguments))); 
}; 
fNOP.prototype = this.prototype; 
fBound.prototype = new fNOP(); 
return fBound; 
}; 
} 
</script>
